Solution:

The shopkeeper sells 12kg of potatoes for 63rs i.e 1kg for 5.25rs
Let cost price = 100x. As he gains 5% the equation can be written as,
105x = 5.25rs (or) 100x = 5rs
∴ Cost price = 5rs
He sells 50 kg of the same potatoes for 247.50rs (or) 1kg = 4.95rs
Gain or loss percentage =

({4.95−5/5})(100)

= 0.05 x 100 = -1%
There will be a loss of 1%
Hence, option B is the correct answer.
